Is it possible that with out crawling it will give pr ??
No I have checked. There is no page cached by google.

Crawling is for content but PR and especially toolbar PR is based on links and if you have too many links pointing to a page it can always get the PR despite the content being only the login box or some error message.

Thanks for your valuable information..But I am thinking first make asearch engine friendly site and that only help us to list our site in server database and then only a user can get our site on their desktop...
